Using #!/usr/bin/expect and bash

Question

Is there any way I can use bash script along with /usr/bin/expect commands?

Could I, for instance, use an if statement in a usr/bin/expect script?

Answer 1

expect is an extension of tcl - therefore you can use the programming constructs of tcl - these include 'if'.

Tcl command man pages are available: tcl.tk/man/tcl8.5/TclCmd/contents.htm

Answer 2

Here is a very simple script that connects to a server via ssh from bash:

#!/bin/bash

/usr/bin/expect <<EOF
    spawn ssh user@server
    expect {
        "assword:" {
            send -- "1234\r"
        }
    }
EOF
